United Airlines will introduce three new domestic routes from San Francisco International Airport beginning March 28, 2027. Service will start to Charleston, South Carolina; Hartford, Connecticut; and Oklahoma City. Charleston flights are seasonal, operating until November 30, 2027, while the Hartford and Oklahoma City routes are planned to run year-round. None of these three cities currently have nonstop flights to San Francisco.
Additional Seasonal Routes Operated with Air Canada
In partnership with Air Canada, United Airlines will also launch three seasonal services next year. Daily flights from Denver International Airport to Ottawa will operate between April 29, 2027, and October 31, 2027. The Denver to Quebec City
route will run Saturdays only from May 29, 2027, through October 30, 2027. Additionally, seasonal Saturday-only flights between Newark Liberty International Airport and St. John’s will be available from June 24, 2027, until September 7, 2027. Tickets for all six new routes are currently available for purchase.
